1 FIELD OF THE INVENTION

The present invention is directed to methods for the use of 5′-adenosine diphosphate ribose (ADPR), and compositions thereof, for treating, managing, or preventing RNA virus-related diseases or conditions, herpes virus related diseases or conditions, Sirtuin 6 (Sirt6)-related diseases or conditions, Pax6 related diseases or conditions, and p53 related diseases or conditions.

2 BACKGROUND OF THE INVENTION

An RNA virus is a virus that has RNA (ribonucleic acid) as its genetic material. This nucleic acid is usually single-stranded RNA (ssRNA) but may be double-stranded RNA (dsRNA). Notable human diseases caused by RNA viruses include bronchitis and bronchiolitis (human respiratory syncytial virus and others), hemorrhagic fever (Ebola virus and others), severe acute respiratory syndrome (coronavirus), the common cold (rhinovirus, parainfluenza virus, corona virus, and others), influenza, hepatitis C, West Nile fever, polio, measles, and acquired immunodeficiency syndrome (human immunodeficiency virus).

Human respiratory syncytial virus (HRSV) is a well-established infectious agent in both immunocompetent as well as immunocompromised individuals. HRSV is a single stranded, negative sense, RNA virus. HRSV typically causes respiratory tract infections that effect all portions of the respiratory tract. HRSV is major cause of lower respiratory tract disease, bronchiolitis and pneumonia, in infants and children. In the United States, 60% of infants are infected during their first RSV season, and nearly all children will have been infected with the virus by 2-3 years of age. Of those infected with HRSV, 2-3% will develop bronchiolitis, necessitating hospitalization. Natural infection with HRSV induces protective immunity which wanes over time—possibly more so than other respiratory viral infections—and thus people can be infected multiple times. Sometimes an infant can become symptomatically infected more than once, even within a single HRSV season. Severe HRSV infections have increasingly been found among elderly patients. Young adults can be re-infected every five to seven years, with symptoms typically looking like a sinus infection or a cold (infections can also be asymptomatic). The incubation time (from infection until symptoms arrive) is 4-5 days. For adults, HRSV produces mainly mild symptoms, often indistinguishable from common colds and minor illnesses. The Centers for Disease Control consider HRSV to be the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia in children under 1 year of age in the United States (Hall et al., 2009, N. Engl. J. Med., 360(6):588-598; Iwane et al., 2013, J. Infect. Dis., 208(Suppl. 3): 2-3; Rose et al., 2018, Respiratory Syncytial Virus Seasonality—United States, 2014-2017, MMWR Morb. Mortal Wkly. Rep., 67:71-76). For some children, HRSV can cause bronchiolitis, leading to severe respiratory illness requiring hospitalization and, rarely, causing death. This is more likely to occur in patients that are immunocompromised, or infants born prematurely. Other HRSV symptoms common among infants include listlessness, poor or diminished appetite, and a possible fever. According to a study by Falsey (Falsey et al., 2005, N. Engl. J. Med., 352(17):1749-1759), over four winter respiratory seasons in Rochester, N.Y. (1999-2003), HRSV infection developed annually in an average of 5.5 percent (range, 3 to 7 percent) of healthy adults age 65 years and older (i.e., without COPD or CHF) and 4 to 10 percent of high-risk adults age 21 years and older (i.e., diagnosed with chronic heart or lung disease). In this same population, HRSV was responsible for 9.6 percent of these hospitalizations. Based on discharge diagnosis, HRSV accounted for 10.6 percent of hospitalizations for pneumonia, 11.4 percent for chronic obstructive pulmonary disease (COPD), 7.2 percent for asthma, and 5.4 percent for congestive heart failure (CHF). In adults, age 65 and over, HRSV infection, based on data from the Centers for Disease Control and Prevention (CDC), is estimated to cause 14,000 annual deaths in US adults.

Herpesviridae is a large family of DNA viruses that cause diseases in animals and humans. The members of this family are also known as herpes viruses. The Greek derivation of the herpes name refers to the latent, recurring infections typical of this group of viruses. Herpes viuses can cause latent or lytic infections. At least five species of Herpes viruses—herpes simplex virus 1 and 2 (known as HSV-1 and HSV-2), varicella zoster virus (the cause of chickenpox and shingles), Epstein-Barr virus (implicated in several diseases, including mononucleosis and some cancers), and cytomegalovirus—are extremely widespread among humans. More than 90% of adults have been infected with at least one of these, and a latent form of the virus remains in most people. There are 9 herpes virus types known to infect humans: HSV-1 and HSV-2, (also known as HHV1 and HHV2), varicella-zoster virus (VZV, which may also be called by its ICTV name, HHV-3), Epstein-Barr virus (EBV or HHV-4), human cytomegalovirus (HCMV or HHV-5), human herpesvirus 6A and 6B (HHV-6A and HHV-6B), human herpesvirus 7 (HHV-7), and Kaposi's sarcoma-associated herpesvirus (KSHV, also known as HHV-8).

Reduced activity of the protein sirtuin 6 (Sirt6) has been associated with multiple diseases, such as viral diseases, diseases due to aging, diabetes mellitus, type 2 diabetes mellitus, respiratory disorders, chronic lung disease, chronic obstructive pulmonary disease, asthma, idiopathic pulmonary fibrosis, cystic fibrosis, ocular disorders, diabetic retinopathy, retinal disease, retinal detachment, adult macular degeneration, glaucoma, liver disease, non-alcoholic steatohepatitis, chronic hepatitis infection, neurodegenerative disorders (e.g., Alzheimer's disease), disorders resulting in cognitive decline, trauma resulting in brain or spinal cord injury, cancer, a chemotherapy-induced neuropathy, neuropathy associated with an ischemic or traumatic event, an autoimmune disorder, disorders associated with excessive inflammation, dental pulpitis, a mitochondrial disease or disorder, cardiovascular disease, stroke, disorders associated with stress, arthritis, osteoarthritis, preterm labor, a disorder that would benefit from decreased cellular glycolytic activity, muscle tissue damage associated with hypoxia or ischemia, a blood coagulation disorder, a fungal infection, ischemia, chronic pain associated with brain and/or spinal cord disease, hypertension, or any combination thereof.

PAX6 (also known as paired box protein Pax-6, aniridia type II protein (AN2) or oculorhombin), a transcription factor that has been highly conserved during evolution, is a key regulator of eye development in both vertebrates and invertebrates. During embryonic development, the PAX6 protein is thought to turn on (activate) genes involved in the formation of the eyes (Kroeber et al., 2010, Human Molecular Genetics, 19(17):3332-3342; Shaham et al., 2012, Progress in Retinal and Eye Research, 31(5):351-376; Swisa et al., Journal of Clinical Investigation, 127(1):230-243; Osumi et al., 2008, Stem Cells, 26(7):1663-1672), the brain and spinal cord (central nervous system), and the pancreas. After birth, continued PAX6 expression throughout life is critical to maintaining the proper phenotype of these cells and helping to avoid metaplastic responses following cellular injury. In humans, heterozygous mutations in PAX6 are causative for aniridia, a condition associated with a variety of ocular developmental anomalies including deficiency or hypoplasia of the iris, corneal opacities, foveal and optic nerve dysplasia and cataract. More rarely, mutations in PAX6 lead to Peters' anomaly, a condition that is characterized by a central corneal opacity (leukoma), a local absence of the corneal endothelium (to which the lens may adhere to) and iridocorneal adhesions. In mice with heterozygous mutations in Pax6, ocular defects are in general more extreme. In most cases, the eyes are less than half of their normal size (microphthalmos), the anterior chamber of the eye is missing, the retina is abnormally folded and the lens is absent or small and has anterior cataracts. About 50-75% of patients with aniridia develop an increase in intraocular pressure (TOP) in preadolescent or early adult years that commonly leads to optic nerve damage and glaucoma. TOP is generated via the aqueous humor circulation system. Aqueous humor is secreted by the ciliary processes into the posterior chamber of the eye and leaves the eye through the trabecular meshwork and Schlemm's canal, which are both localized at the iridocorneal angle of the anterior chamber. Studies in heterozygote Pax6-deficient mice, an animal model of aniridia, have identified defects in trabecular meshwork differentiation and the complete absence of Schlemm's canal. Similar structural defects may well account for the increase in TOP and the glaucoma phenotype, which are observed in humans with aniridia.

Cells in our body are constantly exposed to various stresses and threats to their genomic integrity (Li et al., 2015, Journal of Cellular Physiology, 230(10):2318-2327). The tumor suppressor protein p53 (also known as TP53) plays a critical role in successful defense against these threats by inducing apoptotic cell death or cell cycle arrest. p53 has also been shown to be critical for normal immune responses and modulation of inflammatory diseases. It also plays important roles in metabolism, stem cell maintenance, fertility, and the response to viral and other microbial infection (Munoz-Fontela et al., 2016, Nature Reviews Immunology, 16(12):741-750). In unstressed conditions, p53 levels and activity must be kept low to prevent lethal activation of apoptotic and senescence pathways (Haupt et al., 1997, Nature, 387(6630):296-299). However, upon DNA damage or other stressors, p53 is released from its inhibitory state to induce an array of innate immune, cell cycle, apoptosis, and other regulatory and transcription genes. The ubiquitin E3 ligase MDM2 (murine double minute 2 protein) is the most critical inhibitor of p53 that determines the cellular response to various p53-activating agents, including DNA damage. MDM2 activity is controlled by post-translational modifications such as phosphorylation. MDM2 activity can also be directly inhibited by small molecules that interfere with its interaction with p53 (Shangary and Wang, 2009, Annual Review of Pharmacology and Toxicology, 49:223-241) or by inhibiting its heterodimer formation with MDM4 (also known as MDMX) (Roxburgh et al., 2012, Carcinogenesis, 33(4):791-798). Deficiency of p53 is associated with susceptibility to cancer, impaired innate immunity, susceptibility to viral infection, impaired recovery from bacterial infection, impaired wound healing, increased cataract formation, vascular disease, and abnormal aging of tissues (Madenspacher et al., 2013, The Journal of Experimental Medicine, 210(5):891-904; Wiley et al., 2011, Disease Models & Mechanisms, 4(4):484-495; Tabas, 2001, Circulation Research, 88(8):747-749; Hirota et al., 2010, Journal of Clinical Investigation, 120(3):803-815).

5′-adenosine diphosphate ribose (ADPR) is a naturally occurring small molecule, which is also available commercially. Previous studies have shown that ADPR inhibits Sirt6 at concentrations between 10 to 1000 μM (Madsen et al., 2016, J. Biol. Chem., 291(13):7128-7141).

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a graph of luminescence vs. concentration of dilithium ADPR (Li₂-ADPR). The amount of luminescence directly quantitates the amount of HRSV replication in A549 cells. The results show a significant dose-dependent inhibition of HRSV replication with increasing concentrations of Li₂-ADPR. The pattern of inhibition was similar on days 1 and 2 following the initial infection on Day 0.

FIG. 2 is a graph of the percentage of A549 cells infected vs. the concentration of Li₂-ADPR. Cell infection was determined by the presence of green fluorescence in each cell. The data show that increasing concentrations of Li₂-ADPR results in a significant reduction in the percentage of cells infected on days 1 and 2 following the primary inoculation on day 0.

FIG. 3 is a graph of the percentage of primary human airway epithelial cells infected vs. the concentration of Li₂-ADPR. Cell infection was determined by the presence of luciferase activity. The data show that increasing concentrations of Li₂-ADPR results in a significant reduction in the percentage of cells infected on days 1 and 3 following the primary inoculation on day 0.

FIG. 4 depicts plate images from the plaque inhibition assay described in Example 4.

FIG. 5 shows the gel (a) and quantitative evaluation of Sirt6 deacetylation activity (b) in the presence of Li₂-ADPR. In this example, deacetylation activity is expressed as the inverse of H3K9Ac acetylation (as indicated by anti-H3K9Ac antibody) divided by the total H3 histone concentration. This was then converted to percent.

FIG. 6 shows the mean results of the Sirt6 activation study with Li₂-ADPR concentrations between 0.01 nM and 1000 nM (0.00001 μM and 1 μM).

FIG. 7 shows the time dependent increase in protein concentration for Sirt6 in human corneal epithelial cells incubated with Li₂-ADPR at 60 μM.

FIG. 8 shows the time dependent increase in protein concentration for Pax6 (isoforms 5a and 6) and cytokeratin 12 in human corneal epithelial cells incubated with Li₂-ADPR at 60 μM. All band intensities were calculated relative to “no treat.”

FIG. 9 shows the time dependent increase in protein concentration for p53 human corneal epithelial cells incubated Li₂-ADPR at 60 μM.

FIG. 10 shows an image of the in-silico docking of ADPR with MDM2 at the protein interface between MDM2 and MDM4 as a heterodimer (a) and at the protein binding interface between MDM2 and p53 (b).

FIG. 11 shows results the results for lung tissue RSV titer (a), lung tissue interferon gamma (IFNγ) (b) and lung tissue transforming growth factor beta (TGFβ) (c). Each figure compares the results from control (phosphate buffered saline) and 0.5% Li₂-ADPR treated cotton rats. Tissue samples were obtained on Day 5 of treatment (50 microliters by nasal inhalation given 2 times per day) following infection with RSV.

FIG. 12 shows the effect of Li₂-ADPR on plaque inhibition against HSV-1, performed in A549 cells.

Capsules, blisters, and cartridges for use in an inhaler or insufflator can be formulated to contain a powder mix of the pharmaceutical compositions provided herein; a suitable powder base, such as lactose or starch; and a performance modifier, such as 1-leucine, mannitol, or magnesium stearate. The lactose may be anhydrous or in the form of the monohydrate. Other suitable excipients or carriers include, but are not limited to, dextran, glucose, maltose, sorbitol, xylitol, fructose, sucrose, and trehalose. The pharmaceutical compositions provided herein for inhaled/intranasal administration can further comprise a suitable flavor, such as menthol and levomenthol; and/or sweeteners, such as saccharin and saccharin sodium.

5.6.3 Oral Formulations

Pharmaceutical compositions that are suitable for oral administration can be provided as discrete dosage forms, such as, but not limited to, tablets (e.g., chewable tablets), caplets, capsules, and liquids (e.g., flavored syrups). Such dosage forms contain predetermined amounts of active ingredients, and may be prepared by methods of pharmacy well known to those skilled in the art.

Oral dosage forms provided herein are prepared by combining the active ingredients in an intimate admixture with at least one excipient according to conventional pharmaceutical compounding techniques. Excipients can take a wide variety of forms depending on the form of preparation desired for administration. For example, excipients suitable for use in oral liquid or aerosol dosage forms include, but are not limited to, water, glycols, oils, alcohols, flavoring agents, preservatives, and coloring agents. Examples of excipients suitable for use in solid oral dosage forms (e.g., powders, tablets, capsules, and caplets) include, but are not limited to, starches, sugars, micro-crystalline cellulose, diluents, granulating agents, lubricants, binders, and disintegrating agents.

In one embodiment, oral dosage forms are tablets or capsules, in which case solid excipients are employed. In another embodiment, tablets can be coated by standard aqueous or non-aqueous techniques. Such dosage forms can be prepared by any of the methods of pharmacy. In general, pharmaceutical compositions and dosage forms are prepared by uniformly and intimately admixing the active ingredients with liquid carriers, finely divided solid carriers, or both, and then shaping the product into the desired presentation if necessary.

For example, a tablet can be prepared by compression or molding. Compressed tablets can be prepared by compressing in a suitable machine the active ingredients in a free-flowing form such as powder or granules, optionally mixed with an excipient.

Examples of excipients that can be used in oral dosage forms provided herein include, but are not limited to, binders, fillers, disintegrants, and lubricants. Binders suitable for use in pharmaceutical compositions and dosage forms include, but are not limited to, corn starch, potato starch, or other starches, gelatin, natural and synthetic gums such as acacia, sodium alginate, alginic acid, other alginates, powdered tragacanth, guar gum, cellulose and its derivatives (e.g., ethyl cellulose, cellulose acetate, carboxymethyl cellulose calcium, sodium carboxymethyl cellulose), polyvinyl pyrrolidone, methyl cellulose, pre-gelatinized starch, hydroxypropyl methyl cellulose, (e.g., Nos. 2208, 2906, 2910), microcrystalline cellulose, and mixtures thereof.

Suitable forms of microcrystalline cellulose include, but are not limited to, the materials sold as AVICEL-PH-101, AVICEL-PH-103 AVICEL RC-581, AVICEL-PH-105 (available from FMC Corporation, American Viscose Division, Avicel Sales, Marcus Hook, Pa.), and mixtures thereof. A specific binder is a mixture of microcrystalline cellulose and sodium carboxymethyl cellulose sold as AVICEL RC-581. Suitable anhydrous or low moisture excipients or additives include AVICEL-PH-103™ and Starch 1500 LM. Other suitable forms of microcrystalline cellulose include, but are not limited to, silicified microcrystalline cellulose, such as the materials sold as PROSOLV 50, PROSOLV 90, PROSOLV HD90, PROSOLV 90 LM, and mixtures thereof.

The binder or filler in pharmaceutical compositions is, in one embodiment, present in from about 50 to about 99 weight percent of the pharmaceutical composition or dosage form.

In certain embodiments, fillers may include, but are not limited to block copolymers of ethylene oxide and propylene oxide. Such block copolymers may be sold as POLOXAMER or PLURONIC, and include, but are not limited to POLOXAMER 188 NF, POLOXAMER 237 NF, POLOXAMER 338 NF, POLOXAMER 437 NF, and mixtures thereof.

In certain embodiments, fillers may include, but are not limited to isomalt, lactose, lactitol, mannitol, sorbitol xylitol, erythritol, and mixtures thereof.

Disintegrants may be used in the compositions to provide tablets that disintegrate when exposed to an aqueous environment. Tablets that contain too much disintegrant may disintegrate in storage, while those that contain too little may not disintegrate at a desired rate or under the desired conditions. Thus, a sufficient amount of disintegrant that is neither too much nor too little to detrimentally alter the release of the active ingredients may be used to form solid oral dosage forms. The amount of disintegrant used varies based upon the type of formulation, and is readily discernible to those of ordinary skill in the art. In one embodiment, pharmaceutical compositions comprise from about 0.5 to about 15 weight percent of disintegrant, or from about 1 to about 5 weight percent of disintegrant.

Disintegrants that can be used in pharmaceutical compositions and dosage forms include, but are not limited to, agar-agar, alginic acid, calcium carbonate, microcrystalline cellulose, croscarmellose sodium, povidone, crospovidone, polacrilin potassium, sodium starch glycolate, potato or tapioca starch, other starches, pre-gelatinized starch, other starches, clays, other algins, other celluloses, gums, and mixtures thereof.

Grace Co. of Baltimore, Md.), a coagulated aerosol of synthetic silica (marketed by Degussa Co. of Plano, Tex.), CAB-O-SIL (a pyrogenic colloidal silicon dioxide product sold by Cabot Co. of Boston, Mass.), and mixtures thereof. If used at all, glidants may be used in an amount of less than about 1 weight percent of the pharmaceutical compositions or dosage forms into which they are incorporated.

Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active ingredient, the liquid dosage forms may contain inert diluents commonly used in the art, such as, for example, water or other solvents, solubilizing agents, and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols, and fatty acid esters of sorbitan, and mixtures thereof.

Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming, and preservative agents.

Suspensions, in addition to the active inhibitor(s) may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.

6 EXAMPLES 6.1 Example 1. Inhibition of HRSV Replication by Li₂-ADPR in A549 Cells

Drug Preparation and Handling: Li₂-ADPR, 250 mg, in one glass vial, was received as a powder and stored at −20° C. in the dark until use. On the day of the experiment, Li₂-ADPR was solubilized to 250 mg/ml using 1 ml of autoclaved, distilled, and deionized water. Solubilized Li₂-ADPR was further diluted to target concentrations of 2.7 mg/ml, 0.9 mg/ml, 0.3 mg/ml, and 0.1 mg/ml in virus growth media (DMEM, 2.5% Fetal Bovine Serum and antibiotic).

Inoculation and Treatment: 250 pfu (plaque-forming unit) of RSV encoding a Renilla Luciferase reporter gene was used to inoculate A549 cells in a 96-well plate for 2 hours at 37° C. Afterwards, the inoculum was replaced with 200 μl of fresh virus growth medium containing the target concentrations of Li₂-ADPR described above and incubated at 37° C. Fresh media containing the same target drug concentrations were added to remaining samples each day. At 24 and 48 hours post infection, cells were lysed and assayed for luciferase, as described by the manufacturer (Renilla Luciferase Assay System; Promega). Samples were transferred to a 96-well solid black plate and luminescence was quantified using a PE Wallac Victor 2 1420-012 system microplate reader. Assays were performed in triplicate. Data was plotted using GraphPad Prism software.

Conclusion: Li₂-ADPR was capable of inhibiting RSV replication in A549 cells. The effects were dose-dependent with the greatest inhibition of RSV replication observed when the highest concentration of drug (2.7 mg/ml; ˜five-fold difference) was used. Inhibition of RSV replication was also observed at the lowest concentration of drug (0.1 mg/ml; ˜two-fold difference).

6.2 Example 2. Reduction of HRSV Cellular Infection by Li₂-ADPR in A549 Cells

Images: 250 pfu (plaque-forming unit) of RSV encoding a Green Fluorescent Protein reporter gene was used to inoculate A549 cells in a 96-well plate, as for Example 1 (above). Images were taken every day at the same time points as above. Bright field and fluorescence images were taken at 10× magnifications using an EVOS fl AMG digital inverted microscope. Infected cells were counted.

Conclusion: Li₂-ADPR significantly reduced the percentage of A549 cells infected with HRSV. The effects were dose-dependent with the greatest reduction of HRSV infection observed when the highest concentration of drug (2.7 mg/ml; ˜85% reduction) was used. Inhibition of HRSV replication was also observed at the lowest concentration of drug (0.1 mg/ml; ˜50% reduction).

6.3 Example 3. Reduction of HRSV Cellular Infection by Li₂-ADPR in Primary Human Airway Epithelial Cells

Drug Preparation and Handling: Li₂-ADPR, 250 mg, in one glass vial, was received as a powder and stored at −20° C. in the dark until use. Li₂-ADPR was solubilized to 250 mg/ml using 1 ml of autoclaved, distilled, and deionized water. Solubilized Li₂-ADPR was further diluted to target concentrations of 2.7 mg/ml and 0.9 mg/ml in virus growth media (DMEM, 2.5% Fetal Bovine Serum and antibiotic).

Inoculation and Treatment: 250 pfu (plaque-forming unit) of RSV encoding a Renilla Luciferase reporter gene was used to inoculate the apical surface of human airway epithelial (HAE) cultures for 2 hours at 37° C. Afterwards, the inoculum was removed and 500 μl of fresh HAE growth media containing the indicated concentrations of Li₂-ADPR was added to the basolateral surface of the cultures. Cultures were incubated at 37° C. Fresh media containing the target drug concentrations were added to the cultures each day. Data was plotted using GraphPad Prism software.

Virus Replication/Spread Assay: At 24 and 72 hours post inoculation, cultures were lysed and assayed for luciferase activity as described by the manufacturer (Renilla Luciferase Assay System; Promega). They were then transferred to a 96-well solid black plate and luminescence was quantified using a PE Wallac Victor 2 1420-012 system microplate reader. Assays were performed in triplicate.

Conclusion: Li₂-ADPR was capable of significantly inhibiting RSV replication in HAE cultures. The effects were dose-dependent with the greatest inhibition of RSV replication observed when the highest concentration of drug (2.7 mg/ml) was used.

6.4 Example 4. Effect of ADPR (Sodium Salt) on Plaque Inhibition Against Herpes Simplex Virus Type 1 (HSV-1), Strain KOS

Background: Adenosine 5′-diphosphoribose Sodium Salt, Sigma A0752-100 mg, Lot SLBJ4805V, in one 100 mg vial (“Sample”) was solubilized to concentration 120 mg/ml in water for irrigation. Herpesvirus plaque inhibition assay were set up on the same day. The remainder of the solubilized Sample was placed in dark at 4° C. until use.

Dilutions: Sample solution was diluted 1:40 in virus growth media for the first Sample dilution of 3 mg/ml. Five additional step dilutions were made in the specific virus growth medium to generate 1 mg/ml, 300 μg/ml, 100 μg/ml, 30 μg/ml, and 10 μg/ml, and 6-well plates labeled per Table 1.

TABLE 1 Sample Labeling Sample Label on Sample plate photographs Concentration 1PR (HSV) 3 mg/ml 2PR (HSV) 1 mg/ml 3PR (HSV) 300 μg/ml 4PR (HSV) 100 μg/ml 5PR (HSV) 30 μg/ml 6PR (HSV) 10 μg/ml

Approach: Vero cells were plated at 1×10⁵ per cm² in 6-well plates. After 18 hours growth media was removed from each prepared cell well and 1 ml of each Sample dilution was added. After incubating one hour at 37° C., approximately 60 plaque forming units HSV-1 strain KOS were added per well. Virus was permitted to adsorb to the cells for two hours and then the media was aspirated from the monolayers and replaced with herpes growth media containing Sample dilutions per Table 1, and agarose. After incubating three days at 37° C., monolayers were fixed, agarose removed, stained with crystal violet, and plaques counted.

See plaque counts in Table 2 and plate images in FIG. 4.

Toxicity: Toxicity was evaluated against the below criteria and recorded in Table 2, and used to assess the effects of the dilutions of Sample on cell monolayers at the termination of the assay on the end day.

-   -   0—No Cytotoxicity     -   1—Slight Thinning of Cells compared to Cell Control wells     -   2—Moderate thinning of cells compared to Cell Control wells,         moderately less intense staining of cells compared to Cell         control wells, viral plaques are visible     -   3—Extreme thinning of cells compared to Cell Control wells to no         cells present, extremely less intense staining of cells compared         to Cell Control wells to no staining due to lack of cells, viral         plaques are not visible.

Results: There was inhibition of plaque number and plaque size at the highest Sample dilution 3 mg/ml, with lesser effects at lower concentrations. The monolayer was not affected as judged under the microscope by 3 mg/ml Sample dilution prior to fixation, but was somewhat friable and detached when the agarose layer was flicked off.

6.5 Example 6.5 Sirt6 Activation by Liz-ADPR

Previous studies (Pan et al., 2011, J. Biol. Chem., 286(16):14575-14587) have indicated that ADPR, as a distinct entity, forms during the enzymatic reaction wherein the Sirt6-dependent histone deacetylation reaction produces O-acetyl-ADPR from nicotinamide-adenine-dinucleotide (NAD+) and the acetyl group attached to the lysine side chain of a protein or peptide substrate.

In keeping with the above observations, previous reports have indicated that ADPR inhibits Sirt6 deacetylation activity at concentrations greater than 1 mM (see Sirt6 assay published by Cerep/Eurofins with reference to Michishita et al., 2008, Nature, 452(7186):492-496). In addition, ADPR has been shown to inhibit the deacetylation reaction of a related sirtuin (Khan and Lewis, 2005, J. Biol. Chem., 281(17), 11702-11711.) known as Hst2. Hst2 is the yeast homolog of Sirtuin 2, and it has been the subject of structural, mutagenesis, and kinetic studies given its high degree of conservation and in vitro catalytic activity. In vivo, Hst2 appears to play similar roles as Sirtuin 2.

However, in eukaryote cells (Heiner, 2006, Biochem. J., 398(2):225-232), unbound ADPR concentrations are approximately 5 μM, and concentrations in the nucleus (Sirt6 protein resides almost exclusively in the nucleus) are likely to be considerably lower.

In contrast to what has previously been described, it has been surprisingly discovered that at low concentrations, ≤1 μM, ADPR increases Sirt6 activity. This was demonstrated in two sets of studies. This first set of studies was performed using a Western blot method (Rahnasto-Rilla, 2016, Methods Mol. Biol., 1436:259-269) for the in vitro evaluation of Sirt6 deacetylation activity. Serially diluted concentrations of Li₂-ADPR were incubated for 30 min at 37° C. in the presence of 1 μg/well of a purified recombinant GST-SIRT6 protein, 2 μg purified whole chicken core histones with 500 μM NAD+ in 25 mM Tris-HCl, pH 8.0. Acetylation level was detected with anti-H3K9Ac antibody and normalized to total H3 histone (FIG. 5 (b)). Values indicate final Li₂-ADPR concentration in micromoles per liter (μM). The results (FIG. 5) demonstrate increasing activation of Sirt6 deacetylation activity between 0.01 and 1 μM, with variable activity at concentrations of 10 μM and above.

This study was then repeated focusing on lower ranges of Li₂-ADPR concentrations. In the repeat study, the ratio of H3K9Ac to total H3 (shown on the vertical axis of FIG. 6 as H3K9Ac/H3) was significantly reduced at 0.1 and 1 μM. The second experiment was repeated three times (FIG. 6) and definitively proved that Li₂-ADPR concentrations between 0.1 and 1 μM increase the rate of Sirt6 deacetylation activity.

6.6 Example 6.6 Sirt6 Expression

Sirt6 expression using western blots was evaluated in human corneal epithelial cells.

Cell Culture: Human corneal epithelial cells (ATCC) were grown to just below confluency (80-90%) at 37° C., 5% CO₂. They were washed twice with sterile phosphate buffered saline (PBS) and serum starved for 2 hours at 37° C. Serum starvation media was aspirated and cells were treated with corresponding Li₂-ADPR treatment at 60 μM in serum starvation media. They were incubated for either 15, 30, 60 or 120 minutes with treatment. After each time point, treatment was aspirated and cells were washed twice with ice cold PBS. Cells were lysed in ice-cold cell lysis buffer and rotated end-over-end at 4° C. for 30 minutes. They were then centrifuged at 14,000 g for 30 minutes at 4° C. Supernatants were collected and total protein concentration for each sample was measured using spectrophotometric methods. Samples were stored frozen at −20° C. until performing the Western Blot.

Western Blot: Samples were prepared in 2× Laemmli sample buffer and boiled at 95° C. for 5 minutes. 20 μg protein was loaded into each lane of an 8% tris-glycine gel. Proteins were electrophoresed at 125V for approximately 50 minutes then transferred to nitrocellulose. After blocking the blot for 1 hour at room temperature in 3% BSA in a standard mixture of tris-buffered saline and Polysorbate 20 (TBST), primary antibody (anti-Sirtuin 6) was added in blocking buffer and incubated overnight at 4° C. The blot was washed 3 times with TBST and HRP-linked secondary antibody added at 1:2000 for 40 minutes at room temperature. The blot was again washed 3 times with TBST and developed with ECL reagents for 1 minute. Images were obtained with ChemiDoclt Imager (UVP, Upland Calif.) with exposures ranging from 30 seconds to 5 minutes. Image analysis were done with VisionWorks Software (UVP, Upland Calif.).

The western blot results demonstrate that Sirt6 protein concentration was increased relative to baseline (No Treat lane) to 155% at 30 minutes and 135% at 60 minutes of incubation with Li₂-ADPR at 60 μM. Sirt6 protein concentration then returned to baseline by two hours. The results are shown in FIG. 7.

6.7 Example 6.7 Pax6 and Cytokeratin 12 Expression

Cell Culture: Using a nearly identical method to that described for Sirt6 expression, Pax6 and cytokeratin 12 expression were evaluated in human corneal epithelial cells (ATCC). Cells were grown to just below confluency (80-90%) at 37° C., 5% CO₂. They were washed twice with sterile phosphate buffered saline (PBS) and serum starved for 2 hours at 37° C. Serum starvation media was aspirated and cells were treated with corresponding Li₂-ADPR treatment at 60 μM in serum starvation media. They were incubated for either 15, 30, 60 or 120 minutes with treatment. After each time point, treatment was aspirated and cells are washed twice with ice cold PBS. Cells were lysed in ice-cold cell lysis buffer and rotated end-over-end at 4° C. for 30 minutes. They were then centrifuged at 14,000 g for 30 minutes at 4° C. Supernatants were collected and total protein concentration for each sample was measured using spectrophotometric methods. Samples were stored frozen at −20° C. until performing the Western Blot.

Western Blot: Samples were prepared in 2× Laemmli sample buffer and boiled at 95° C. for 5 minutes. Forty μg protein were loaded into each lane of an 8% tris-glycine gel. Proteins are electrophoresed at 125V for approximately 50 minutes then transferred to nitrocellulose. After blocking the blot for 1 hour at room temperature in 3% BSA in a standard mixture of tris-buffered saline and Polysorbate 20 (TBST), primary antibody (anti-Pax6 or anti-cytokeratin 12) was added in blocking buffer and incubated overnight at 4° C. The blot was washed 3 times with TBST and HRP-linked secondary antibody added at 1:2000 for 40 minutes at room temperature. The blot was again washed 3 times with TBST and developed with ECL reagents for 1 minute. Images were obtained with ChemiDoclt Imager (UVP, Upland Calif.) with exposures ranging from 30 seconds to 5 minutes. Image analysis was done with VisionWorks Software (UVP, Upland Calif.).

The western blot results demonstrate that Pax6 protein (isoforms 5a and 6) concentration was increased dramatically relative to baseline (No Treat lane). For the isoform 5a, protein concentration increased to 188% at 30 minutes and 584% at 60 minutes of incubation with Li₂-ADPR at 60 μM. For the isoform 6, protein concentration increased to 179% at 30 minutes and 302% at 60 minutes of incubation with Li₂-ADPR at 60 μM. Both isoforms decreased somewhat at two hours with isoform 5a at 206% and isoform 6 at 197% of baseline. Cytokeratin 12 was also evaluated. Both the monomer and dimer forms of cytokeratin 12 were increased at 30, 60, and 120 minutes relative to baseline. The monomer form was at 269% at 30 minutes, 789% at 60 minutes, and 505% at 120 minutes. The dimer form of cytokeratin 12 was at 139% at 30 minutes, 219% at 60 minutes, and 201% at 120 minutes. The results are shown in FIG. 8.

6.8 Example 6.8 ADPR Inhibits MDM2 Thereby Increasing p53

Cell Culture: Using a nearly identical method to that described for Sirt6 expression, p53 expression was evaluated in Human corneal epithelial cells (ATCC). Cells were grown to just below confluency (80-90%) at 37° C., 5% CO₂. They were washed twice with sterile phosphate buffered saline (PBS) and serum starved for 2 hours at 37° C. Serum starvation media was aspirated and cells were treated with corresponding Li₂-ADPR treatment at 60 μM in serum starvation media. They were incubated for either 15, 30, 60 or 120 minutes with treatment. After each time point, treatment was aspirated and cells are washed twice with ice cold PBS. Cells were lysed in ice-cold cell lysis buffer and rotated end-over-end at 4° C. for 30 minutes. They were then centrifuged at 14,000 g for 30 minutes at 4° C. Supernatants were collected and total protein concentration for each sample was measured using spectrophotometric methods. Samples were stored frozen at −20° C. until performing the Western Blot.

Western Blot: Samples were prepared in 2× Laemmli sample buffer and boiled at 95° C. for 5 minutes. Twenty μg protein were loaded into each lane of an 8% tris-glycine gel. Proteins are electrophoresed at 125V for approximately 50 minutes then transferred to nitrocellulose. After blocking the blot for 1 hour at room temperature in 3% BSA in a standard mixture of tris-buffered saline and Polysorbate 20 (TBST), primary antibody (anti-p53) was added in blocking buffer and incubated overnight at 4° C. The blot was washed 3 times with TBST and HRP-linked secondary antibody added at 1:2000 for 40 minutes at room temperature. The blot was again washed 3 times with TB ST and developed with ECL reagents for 1 minute. Images were obtained with ChemiDoclt Imager (UVP, Upland Calif.) with exposures ranging from 30 seconds to 5 minutes. Image analysis was done with VisionWorks Software (UVP, Upland Calif.).

Results: The western blot results demonstrate that p53 protein concentration was rapidly increased relative to baseline (No Treat lane). Protein concentration increased to 313% at 15 minutes, 535% at 30 minutes, 407% at 60 minutes, and 510% at 120 minutes of incubation with Lie-ADPR at 60 μM. The results are shown in FIG. 9. This result definitively demonstrated that ADPR increased protein concentrations of p53, and therefore p53's activation. Once p53 activation was demonstrated, binding of ADPR to MDM2 was evaluated. It is known that MDM2 is the primary inhibitor of p53 activation, and it had been previously published that the purine compounds ATP (adenosine triphosphate) and ADP (adenosine diphosphate) bind to MDM2 in its ring finger domain (Poyurovsky et al., 2003, Molecular Cell, 12(4), 875-887; and Priest et al., 2010, Nucleic Acids Research, 38(21), 7587-7598). Analysis of ADPR binding with MDM2 was undertaken using Swissdock, a protein-small molecule docking web service based on EADock DSS (Grosdidier et al., 2011, Nucleic Acids Research, 39(SUPPL. 2), 270-277). Two previously developed protein models that are publicly available were used for docking. The first analysis evaluated docking of ADPR to the MDM2-MDMX ring domain heterodimer (Linke et al., 2008, Cell Death and Differentiation, 15(5), 841-848). ADPR was successfully docked in the cleft between the protein chains for MDM2 and MDM4 (FIG. 10 (a)). Maximum deltaG (free energy of binding) was −10.58 kcal/mol, which was consistent with the hypothesis that ADPR could inhibit the activity of the heterodimer, and thereby activate p53. Furthermore, ADPR was also shown to bind at the interface between MDM2 and p53 (FIG. 10 (b)). The protein structures used for this modeling were previously developed for analyzing small molecule benzodiazepinedione inhibitors of MDM2 which bind at the alpha helical transactivation domain of p53 (Grasberger et al., 2005, Journal of Medicinal Chemistry, 48(4), 909-912). When ADPR was docked with these proteins, it was found to bind to multiple sites in and around the transactivation domain. Though the maximum deltaG (−8.511 kcal/mol) was less than that observed for binding in the ring finger domain, the finding further indicated the potential for ADPR to inhibit MDM2's effect on p53.

6.9 Example 6.9 Li₂-ADPR Reduces Viral Titer and Modifies Cytokine Response in Cotton Rat RSV Lung Infection

Methods: In view of the reduction in hRSV cellular infection in A549 and human airway epithelial cells, an in vivo experiment in the Cotton Rat was carried out using RSVA2 infection. In this study, adult male cotton rats (6-8 weeks of age) were divided into groups of 4 animals each. Animals were pre-bled for serum collection and ear tagged for identification. All animals were infected via intranasal instillation with 0.1 mL of RSV/A2 at 10⁵ plaque-forming units (pfu) per animal. The design of the study is shown in the following table:

Drug Treatment RSVA2 infection Vol/ Amount Study Gp # n Drug Dose Route Study days (50 μL IN) Day Harvest Day 1 4 PBS BID 50 μL IN 1 hr post 1 × 10⁵ pfu Day 0 Day 5; 2 4 Li₂-ADPR 0.5% soln, 50 μL IN infection 1 × 10⁵ pfu Day 0 Collect serum and BID and then lung BID through Titer lungs Day 4 Animals were treated two times per day by nasal inhalation of either phosphate buffered saline or 0.5% Li₂-ADPR. At each treatment the animals received 50 μL. On day 5, the animals were sacrificed for viral lung titers and cytokine analysis. Interferon gamma (IFNγ) and transforming growth factor beta (TGFβ) gene expression were analyzed by PCR. The cytokine mRNA level was normalized relative to beta actin.

Background: Li₂-ADPR was tested for effects on inhibition of HSV-1 virus plaque formation on A549 cells which are known to express moderate levels of both CD38 and CD157. Again, acyclovir was included as a positive control.

Li₂-ADPR was resolubilized to 100 mg/ml or a 175 mM solution in water for irrigation. This stock solution was used to generate the dilutions of the test sample. The following concentrations of Li₂-ADPR were evaluated: 0.1, 0.4, and 1.2 mM. Acyclovir was tested at 0.002 and 0.05 mM. A control, with no treatment was also evaluated.

Samples at the target concentrations per ml were added to A549 cell monolayers in duplicate in liquid virus growth media for one hour, and then approximately 100 plaque forming units of HSV-1, strain MacIntyre, were added to each monolayer. After virus adsorption, media was removed and monolayers overlaid with semisolid agarose media containing each drug dilution. Monolayers were fixed and stained with crystal violet to visualize virus plaques. Pictures of the test plates were submitted to client for image analysis.

Results: HSV 1 result—The no drug treatment (negative control) showed a monolayer of evenly spaced plaques of one size. The wells treated with 0.05 mM acyclovir showed few small breakthrough plaques. The wells treated with 0.002 mM Acyclovir showed more smaller plaques, but not as many nor as large as the untreated wells. The wells treated with 0.1 mM Li₂-ADPR showed plaques similar in number and size as the untreated wells, but as the drug concentration increased from 0.4 to 1.2 mM, the plaque number decreased and the plaque size decreased. FIG. 12 shows the effect of Li₂-ADPR on plaque inhibition against HSV-1.

Percent plaque area was calculated using ImageJ, version 1.52i. The results for Li₂-ADPR and the No Treatment Control are as follows:

Li₂-ADPR No Treatment 0.1 mM 0.4 mM 1.2 mM Control 8.1% 14.3% 4.8% 18.5% 8.3%  7.3% 3.8% 10.9%

Though there was some variability at 0.4 mM, there was a clear decrease in percent plaque area as the concentration of Li₂-ADPR increased.
